2005 F350 with a crank no start.
During cranking The ICP volts correspond with the rise in pressure then the psi jumps from 500-700 to 8000, 10000+psi and does not start. It blows black smoke and sputters like it is gonna catch but doesn't. Does not start with ICP unplugged either>
FICM Main 48.5 KOEO 48 during cranking. Logic and vehicle are both at 11.5 and go as low as 10.5 during long cranks.
IPR 14.84 KOEO and goes to 48% during cranking
EPB volts are .96
FICM sync YES
CKP/CAM sync YES
MAP 101
BARO 100.76
fuel pressure at 62-64 psi KOEO and during cranking.
OEM fuel/Oil filter (Motorcraft) and motorcraft 15W-40 oil.
HPOP verified to put out 4000+psi and HPOP system air checked and no leaks present. Updated STC, dummy, standpipe.
Basically don't know why this truck won't start?
Only DTC is for glow plugs and a randon B1352-20 and B1360-20 both have to deal with an ignition key in circuit fault

 

Bad IPR? Completely blocked screen or oil passage? The 14.84 and 48 are commands to the IPR no indication of where it's really at. If it's cranking to over 4500 it's not opening. I didn't know it was capable of over 10000 on the starter.

 

I thought so too but IPR is brand new Motorocraft. What do you mean by block oil passage thought. Blocked where in the system?

 

What work/repairs were done recently before the no start?

 

It sounds like FPW needs monitored on this one. If it spits n sputters (like it is trying to start), it's NOT a HPO issue.

Edit,,, I'm crazy,, if its a fpw issue,, it wouldn't spit either,, I will shut up now!! Lol

 

Took IPR out and it had some stuff on it. Cleaned screen and reinstalled, also pressed plunger and blew out valve with brake cleaner and compressed air. reinstalled IPR valve and cranked her up and is at 52% duty cycle. I also checked voltage at the IPR connector KOEO and got battery volts 12.9 is that right?

 

Recently done injector and oil cooler and EGR delete. I filled the reservoir for the oil cooler after installing the screen. I seem to be getting everything i need to start just not starting. Before all the work was done it never blew smoke just cranked and cranked, nw it blows smoke and intermittently tries to fire while cranking.

 

FPW? not sure what you mean Oh just saw edit not an FPW issue

 

I've done a lil playing with testing early pumps. I found out a regular air coupler, coupled to the IPR test fitting and plugged off, explodes and flies across the shop!! Lol. And I had a 4000 psi mechanical gauge threaded into the stand pipe,, (I was making tools that day) and it pegged the gauge and blew a hole in it n shot oil across the shop. If the HPO system is dead headed tight,,, you will notice the starter really strain trying to pump up against a wall. Just some thoughts.

 

Yup, once the system is maxed out with ICP pressure there is a noticeable change is starter/engine cranking. I think the HPO system is tight and makes plenty of pressure. Injectors are new and passes injector test, did bottom o-ring leak check, and bubble test and they all passed.
There is nothing that tell me this thing shouldn't start except for the random B1352 and B1360 codes but I've been told those wouldn't cause a no start.
Starting to think it's PCM but it passes the KOEO PCM check and I've reset all PCM adaptations so it wouldn't duplicate any issue it previously saw

 

Is the air filter good? Does it still have the CAT in the exhaust system?

 

Air filter is new and yes it does have a CAT in the system, it's a totally stoke exhaust? Are you thinking blockage of some sort?

 

Yes I was curious as the CAT's will sometimes plug.

 

If its sputtering,, it's gotta be a fuel issue. Did a line get bent or crushed? Maybe something is clogging the banjos or in the upper fuel housing. I'd pop off the pass banjo and make sure fuel is flowing koeo. How did the filters look when it came in? You could pull the ebp sensor n throw shop air and listen at the tailpipe.

 

I had a truck like this the other day. Was working on it for a buddy. Truck wouldn't crank or anything. Starter was bad. Put a new starter in. It would crank and everything needed to start was achieved but it wouldn't start. I told the owner and he was like yeah it does that, hit it with some ether. I tried explaining to him it was a bad idea and waited till he arrived and let him do it. It fired right up. He says his truck will not start after sitting for a while, like weeks at a time, with out ether. I would not advised this at all. Just sharing my experience. I would think it would have to be something fuel related.
